Jonathan Chase, the CIA's top field agent, is sworn to protect and serve the United States at all costs. But after a brutal period of captivity during the Korean War, Chase developed an agenda of his own: to use his mastery of war to create peace.

His new target: the Zero Directorate, a cabal of rogue assassins who have embarked on a campaign to systematically interrogate and kill seasoned secret agents across the globe.

But the Directorate has set an elaborate trap, and for Chase, the world's preeminent operative, the whole mission involves and inescapable paradox: the closer he gets to the cabal, the closer the cabal gets to its primary target.
